So, the patch set you want to see is: - remove the AAD copy operation from authenc and not add it to any AEAD implementations - add the AAD copy operation to algif_aead Shall the null cipher context we need for that be anchored in the crypto_aead data structure as done in patch 01 of this series (this would allow an easy addition to the copy call to every AEAD implementation if deemed needed) or shall it be anchored within algif_aead?
